Abstract

La5Si5I3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are five inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to five Si+2.40- and three I1- atoms to form a mixture of distorted edge and face-sharing LaSi5I3 hexagonal bipyramids. There are a spread of La–Si bond distances ranging from 3.04–3.13 Å. There are two shorter (3.33 Å) and one longer (3.34 Å) La–I bond lengths. In the second La3+ site, La3+ is bonded in a 9-coordinate geometry to eight Si+2.40- and one I1- atom. There are a spread of La–Si bond distances ranging from 3.12–3.19 Å. The La–I bond length is 3.38 Å. In the third La3+ site, La3+ is bonded in a 8-coordinate geometry to four Si+2.40- and four I1- atoms. There are two shorter (3.10 Å) and two longer (3.11 Å) La–Si bond lengths. There are a spread of La–I bond distances ranging from 3.37–3.68 Å. In the fourth La3+ site, La3+ is bonded in a 10-coordinate geometry to nine Si+2.40- and one I1- atom. There are a spread of La–Si bond distances ranging from 3.16–3.28 Å.
